package/busybox: minor update, some fixes and comments

- update to 1.18.4
- introduce BB_MAKE_FLAGS, simplifying package/busybox/Makefile a bit
- document how the package/busybox/config may be updated
- document what needs to be done so one may drop 003-defaults.patch
- update package/busybox/config, a few busybox features were not
  selectable
